The Yukon 8.6-inch GM wheel-speed reluctor ring is a replacement exciter that installs behind the axle bearing and seal on GM 8.6 in axles. It fits into the space behind the bearing/seal and provides the required reluctor profile for ABS sensor interaction. Yukon supplies this part as part of its small-part line for axle service and wheel-speed sensing restoration.
